Comparing card values of HOF's pre-war vs post war 1950's

[goudey1933]

This is a very broad question open to much discussion.I am comparing more common prewar sets ..T206,T205,Goudey etc. vs 1950's HOf's.Condition wise..low to midgrade.
The reason I'm asking is I look at the values of some mid 50's cards Aaron, Mantle,Clemente, Koufax etc. and the asking price is roughlythe same ballpark as some prewar HOF's I've been looking at for ex.T206 Mathewson lower grade.
In a round about way what I'm asking is this...my collecting is very cyclic...usually within 2-3 years of buying I sell..either to change up the collection or to help finance a non collecting purchase...mountainbike/roadbike upgrades etc.Do you feel the 50's material moves and holds the value as much as some of the more common prewar material.
Apologies again as this is a vary broad question.Almost all of you have more experience then I do as far as buying/selling so i'd like to tap into that experience.
Thanks in advance.
